Everything you need to know about our server racks, networking cabinets, IP-rated outdoor enclosures, custom sheet metal fabrication, and export capabilities — answered by our engineering team at Eterna Global Solutions LLP, Noida.
Server Racks & Enclosures
What is the difference between a wall-mount rack and a floor-standing server rack?
Wall-mount racks (4U–15U) bolt to a wall and are ideal for switches, patch panels, and CCTV equipment in offices; floor-standing racks (22U–47U) stand independently and support full-depth servers, UPS units, and heavy networking gear. Read more ? Wall-mount racks are compact enclosures from 4U to 15U that mount directly to a wall stud or masonry surface. They are designed for networking switches, patch panels, fibre terminations, CCTV NVRs, and small UPS units where floor space is limited — for instance, branch offices, retail back rooms, or corridor comms cupboards. Load capacity is typically 60–80 kg static. Floor-standing server racks (22U–47U) are free-standing enclosures that sit on levelling feet or castors. They support full-depth servers (up to 1,000 mm deep), high-density switching, PDUs, cable management, and cooling hardware, with static load capacities up to 800–1,500 kg depending on the frame gauge and cross-brace design. Eterna manufactures both categories in-house, so we can customise height, depth, width, and load specifications to your exact data centre or IT room requirements. Read less ?
What server rack sizes and U-heights does Eterna manufacture?
Wall-mount racks from 4U to 15U and floor-standing racks from 9U to 47U, with widths of 600 mm or 800 mm and depths from 400 mm to 1,200 mm. Read more ? We manufacture wall-mount racks in standard U-heights of 4U, 6U, 9U, 12U, and 15U. Floor-standing racks are available from 9U up to 47U, with the most common data centre heights being 42U and 47U. Standard widths are 600 mm (networking) and 800 mm (server), with depths from 400 mm for shallow networking to 1,000 mm and 1,200 mm for full-depth server environments. All dimensions follow the 19-inch EIA-310-D mounting standard. If your project requires a non-standard U-height, width, or depth — for example, a 32U rack at 900 mm depth for a specific OEM server chassis — we fabricate to your exact specification with no minimum order on custom sizes. Read less ?
What is the load-bearing capacity of your server racks?
Wall-mount racks support 60–80 kg static; floor-standing racks support 800–1,500 kg depending on frame gauge and configuration. Read more ? Load capacity depends on the rack construction. Our wall-mount racks support 60–80 kg static load, which is adequate for switches, patch panels, and small UPS units. Floor-standing racks are available in standard-duty (800 kg), heavy-duty (1,000 kg), and reinforced (1,500 kg) configurations. The difference is primarily in the frame channel gauge (1.2 mm vs 1.6 mm vs 2.0 mm CRCA), the cross-brace design, and whether the rack uses welded or bolt-together construction. We specify frame gauge based on your equipment weight and whether the rack will support side-mounted PDUs or top-of-rack switching in addition to the main payload. Load capacity is per-rack static load with equipment evenly distributed across mounting rails. Read less ?
Are Eterna racks compatible with standard 19-inch servers and networking equipment?
Yes. All our racks follow the 19-inch EIA-310-D standard, so they accept equipment from Dell, HP, Cisco, Juniper, Aruba, Arista, and all major server and networking brands. Read more ? Every Eterna rack uses 19-inch (482.6 mm) mounting rails compliant with the EIA-310-D international standard. This ensures compatibility with virtually all rack-mount servers, switches, routers, patch panels, UPS units, and PDUs from manufacturers including Dell PowerEdge, HPE ProLiant, Cisco Catalyst and Nexus, Juniper, Aruba, Arista, Lenovo ThinkSystem, Supermicro, APC, and Vertiv. Our mounting rails use standard square-hole (M6 cage nut) or threaded-hole patterns. Rail-to-rail depth is adjustable within the rack to accommodate different server chassis depths. If you are deploying a specific equipment model and want to confirm fitment, share the chassis dimensions and we will verify compatibility against our rack internal geometry before production. Read less ?
Do you manufacture open-frame racks as well as enclosed cabinets?
Yes. We produce 2-post open racks, 4-post open frames, and fully enclosed cabinets with locking doors, side panels, and top covers. Read more ? We manufacture three primary rack formats: (1) 2-post open racks for lightweight networking and patch panel installations where maximum airflow and quick access are priorities; (2) 4-post open-frame racks for heavier servers and switching in environments where physical security is not a concern (e.g., within a locked server room); and (3) fully enclosed cabinets with locking front and rear doors, removable side panels, top fan cut-outs, and cable entry provisions. Enclosed cabinets are available with perforated mesh doors (63–80% open area for passive cooling), glass doors (for visual monitoring), or solid steel doors (for security or EMI shielding). The format is selected based on your security requirements, cooling strategy, and physical environment. Read less ?
IP-Rated & Outdoor Enclosures
What IP-rated enclosures does Eterna manufacture?
We manufacture IP55 and IP65 enclosures for outdoor telecom, industrial, and smart-city deployments — designed for dust, rain, humidity, and extreme Indian temperatures. Read more ? Eterna manufactures IP55 and IP65 rated enclosures for outdoor and harsh-environment installations. IP55 provides protection against dust ingress (limited) and low-pressure water jets from any direction — suitable for covered outdoor locations and semi-exposed environments. IP65 provides complete dust-tight protection and resistance to water jets from all directions — required for fully exposed outdoor installations such as telecom BTS sites, roadside cabinets, railway wayside locations, and smart-city poles. Our IP-rated construction uses continuous EPDM gaskets on all door and panel interfaces, IP-rated cable glands for entry points, rain hoods over ventilation openings, and continuous seam welding on all body joints. We test our sealing design against the relevant IEC 60529 criteria. Enclosures are available in standard sizes or custom-designed to house your specific equipment. Read less ?
Can your outdoor enclosures withstand Indian monsoon and extreme heat conditions?
Yes. Our enclosures are engineered for −5°C to 55°C operating range, monsoon-level rainfall, high humidity, and UV exposure across all Indian climate zones. Read more ? Our outdoor enclosures are designed specifically for the Indian operating environment. Key environmental engineering includes: operating temperature range of −5°C to 55°C (covering Himalayan foothills to Rajasthan desert conditions); monsoon protection via IP65 sealing, rain-hooded vents, and sloped canopy roofs to prevent water pooling; humidity resistance through anti-condensation heaters (optional), sealed gaskets, and proper drainage; UV-resistant outdoor-grade polyester or polyurethane powder coat with UV stabilisers to prevent colour fading and chalking; and corrosion resistance via full 7-tank zinc phosphating pre-treatment achieving 500+ hours salt spray resistance per ASTM B117. For coastal installations (Konkan coast, Chennai, Kerala), we offer SS 304/316 construction or dual-coat systems (epoxy primer + polyester topcoat) for enhanced corrosion protection. Read less ?
What is the difference between IP55 and IP65 protection ratings?
IP55 offers dust protection (limited ingress) and low-pressure water jet resistance; IP65 is fully dust-tight and resists high-pressure water jets. Choose IP65 for fully exposed outdoor sites. Read more ? The IP (Ingress Protection) code has two digits per IEC 60529. The first digit rates solid particle protection: 5 = dust-protected (limited ingress, won’t affect operation), 6 = dust-tight (no ingress at all). The second digit rates water protection: 5 = low-pressure water jets from any direction (12.5 L/min at 3 m), 5 = same, meaning IP55 is dust-protected + jet-resistant. IP65 is dust-tight + jet-resistant. In practical terms: IP55 is suitable for semi-sheltered outdoor installations (under a roof overhang, in a telecom compound with fencing). IP65 is required for fully exposed installations — roadside cabinets, pole-mounted enclosures, open-field BTS sites, and any location where driving monsoon rain can hit the enclosure from any angle. If you are unsure which rating your project requires, share the installation location details and we will recommend the appropriate IP level and construction. Read less ?
Cooling & Thermal Management
What cooling options are available for your server racks and cabinets?
Roof-mount fan trays (2/4/6 fans), perforated doors (63–80% open area), louvred ventilation panels, dust filters, and cable entry brush grommets for controlled airflow. Read more ? Eterna offers multiple cooling and airflow options: (1) Roof-mount fan trays with 2, 4, or 6 fans (120 mm, typically 220V AC) for active exhaust of hot air from the top of the rack; (2) perforated mesh front and rear doors with 63–80% open area for passive front-to-back airflow aligned with server fan intake/exhaust; (3) louvred side and rear ventilation panels for racks where cross-ventilation is preferred; (4) dust filters (G2/G3 washable media) for environments with airborne particulates; and (5) cable entry brush grommets to maintain airflow separation between hot and cold zones while allowing cable passage. For higher heat loads or outdoor enclosures, we integrate provisions for heat exchangers and thermoelectric coolers (customer-supplied units or sourced through our partners). We recommend the right configuration based on your total IT heat load (in watts), ambient temperature, and whether the installation is in an air-conditioned room or an un-cooled environment. Read less ?
Can racks be customised for hot-aisle / cold-aisle data centre airflow?
Yes. We manufacture racks with front-to-back airflow alignment, perforated doors, blanking panels, and brush-grommet cable entry to support hot-aisle/cold-aisle containment strategies. Read more ? We design rack perforation, door open area, blanking panel provisions, and cable routing specifically to support hot-aisle/cold-aisle separation in data centre environments. Key features include: perforated front door aligned with server intake; perforated or open rear for exhaust; blanking panels in every unused U-space to prevent hot air recirculation; brush-grommet cable entry at top and bottom to seal the gap between rack and raised floor or ceiling plenum; and side panel sealing to prevent air bypass between adjacent racks. For aisle containment projects, we can build racks with top panel provisions for containment curtains or rigid containment panels. Share your data centre layout and cooling architecture and we will specify the rack configuration that optimises your PUE. Read less ?
Custom Manufacturing & Sheet Metal Fabrication
Can Eterna manufacture a completely custom-designed rack or enclosure from our drawings?
Yes. As a sheet metal manufacturer, we specialise in custom fabrication — send us your drawings (DXF, DWG, STEP, SolidWorks, or even a sketch) and we build exactly what you need. Read more ? Custom fabrication is our core strength. We manufacture racks, cabinets, and enclosures of any size, configuration, or complexity from your engineering drawings or concept sketches. Our process: (1) you send drawings in DXF, DWG, STEP, IGES, native SolidWorks, or PDF — even a hand-drawn sketch with dimensions; (2) our engineering team reviews for manufacturability (DFM) and provides feedback within 48 hours; (3) we produce a first-article prototype on production CNC machines (10–15 working days); (4) after your approval, batch production begins.

Read less ?
Ordering, Delivery & Export
Are your racks delivered fully assembled or in knock-down (CKD) form?
Both options available. Fully assembled for quick on-site deployment; CKD (flat-packed) for export orders and projects where freight cost or lift access is a constraint. Read more ? We offer both delivery formats: Fully assembled — the rack arrives ready to install. Ideal for domestic projects, single-site deployments, and customers who want immediate rack-and-stack. CKD (Completely Knocked Down) — components flat-packed with all hardware, illustrated assembly instructions, and labelled packages. This format typically reduces shipping volume by 50–60%, which significantly lowers freight cost for export, multi-site rollouts, and high-rise buildings where lift or stairwell access limits assembled rack dimensions. On-site assembly takes 20–30 minutes per rack with basic tools. For export orders, CKD is the default format unless assembled delivery is specifically requested. We also offer SKD (Semi Knocked Down) where the main frame is pre-assembled and panels/doors ship flat. Read less ?
What is the typical delivery timeline for server racks and enclosures?
Standard products: 7–15 working days. Custom-engineered enclosures: 2–4 weeks including DFM review, first article, and production. Read more ? Lead times depend on the order type: Standard catalogue racks (common sizes, standard colour): 7–15 working days from order confirmation. Custom-engineered enclosures (non-standard dimensions, special features): 2–4 weeks, broken down as DFM review (2–3 days) + material procurement if non-stock (5–7 days) + production (7–12 days) + coating and packing (3–5 days). Large-volume orders (100+ racks): phased delivery schedule agreed at order stage, typically first batch in 3 weeks with subsequent batches weekly or fortnightly. Repeat orders with stored CNC programs are faster — typically 7–10 working days. For urgent requirements, we can accommodate rush production on a case-by-case basis. Read less ?
